are optionally substituted hydrocarbon residues, as precursors for radicals useful in reactions triggered by free radicals, such as polymerization of unsaturated monomers and degradation of polyolefins. Most of the triazenes of formula (I) are novel and claimed, too, as well as the preparation of triazenes of formula (I) and polymerisable compositions comprising them.
本发明涉及使用式(I)的三氮烯,其中Q是直接键或二价基团—(CR8R9)—,Z1是—O—,—NR10—,—CH2—,—(CR11R12)—或—C(═O)—,R1到R12是可选的取代烃基,作为自由基引发反应中有用的自由基前体,例如不饱和单体的聚合和聚烯烃的降解。式(I)的大多数三氮烯都是新的,并且也声称了式(I)的三氮烯的制备以及包含它们的可聚合组合物。
